Kid Cudi: Ben Breedlove Is My Hero

The messages on his index cards have already been read by more than a million people and counting.

The words, written in bold black ink, share Ben Breedlove's hopes, dreams and fears about life, death and the heart condition that would ultimately take his life on Christmas Day.

One of the millions moved: hip-hop artist Kid Cudi, who Breedlove said came to him in a vision – a memory he recalled in the sequence of YouTube videos he posted before his death.

"I watched the video he left for the world to see, and him seeing me in detail, in his vision really warmed my heart," Cudi, 27, writes on his blog. "I broke down, I am [brought] to tears."

Breedlove's vision came to him on Dec. 6, or the third time he "cheated death," he wrote. As he was being revived after passing out in the hallways of his high school, he saw Kid Cudi in a bright white room; both are wearing suits.
